Figure 4.

Renal infiltration of macrophages is not different among the groups. Macrophages were immunostained with antibodies directed against F4/80 in renal sections. F4/80⁺ cells (brown cells in the images) were quantified in the renal cortex and outer and inner medulla of DJ‐1 ^−/− and wild‐type mice treated with vehicle or tempol. Cells were quantified per 400×400 mm field (×400 magnification). No differences were found between groups. Data are expressed as mean±SE, n=4 per group.
